JOHN RUEGG, OF ST. LOUISJMISSOUBI.

BRUSH-MACHINE.

Specification of Letters Patent No. 30,353, dated October 9, 1860.

To all whom it may concern:

Be it known that I, JOHN Runes, of St. Louis, Missouri, have invented a new and useful Machine for Trimming Brushes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making part of this specification, in which- Figure 1 is a top view; Fig. 2 a front elevation; Fig. 3 an end elevation, and Figs. l and 5 are detailed parts of the machine to be hereinafter described.

To enable others skilled in the art to which my invention appertains to make and use the same I will proceed to describe the construction and operation thereof.

Similar letters of reference represent corresponding parts of the different figures of the drawing annexed.

The frame of my machine is represented in the drawing by A. It consists of an iron shears, similar to the shears of a turning lathe. Upon this shears a sliding head is mounted, shown by B. In the lower side of this head a dovetail groove is made, to fitover the V slides, which compose the upper part of the shears, in the manner shown in Fig. 3. To the under side of the said head B a pinion rack H is fixed into which the pinion s is made to mesh, so as to move the head to and fro, upon the application of power to the shaft L upon which the said pinion is fixed.

Upon the sliding head B a movable plate B is placed, which is secured in the center, by means of a screw or pin 6, and at the end by means of a screw 0. This plate con sists of a segment of a circular ring, and the concave side thereof is made to act against a stationary pin J fixed to the shears so as to be about in the center of motion of the sliding head, so that when the pin or screw 0 is taken out, and the head moved back and forth, the plate B will be made to oscillate around the center pin 6; by its action against the pin J, upon the upper end of which there is a friction roller 76, placed for the segment plate B to act against.

The object of the sliding head B to carry the brush up to and past the cutter, upon a straight line, so as to cut the face of the brush straight, and the object of the segment plate B on the sliding head, arranged as aforesaid, is to carry the brush past the cutter upon a curved line, so as to cut the face of the brush curved, whenever it may be desired. When the face of the brush is to be cut straight then the screw 0 is to be put in so as to hold the plate fast in a given position, and the friction roller 70 is to be taken off of the top of the pin J so as to allow the plate to pass.

Upon the upper side of the plate B two columns E E are erected, in the top whereof pivots e e are fixed, in between which the plate D is held so that it can vibrate around the said pivots. Upon the back side of this plate D a projection F is made, through which the screw 03 is made to pass, as is also the guide pin a, and over the top of the projection F a plate G is arranged, of the same shape as the said projection. Into this said plate G the screw (l, is fixed so as to carry the said plate up or down whenever the said screw is turned, by the application of power to the crank C. The plate D has a projection on its inside face as shown by 0, and the plate G is'made to roject past the inside face of the plate so as to come flush with the projection 0. Now the object of this movable plate G and the projection 0 on the plate D is to clamp the back of the brush and hold it during the operation of trimming, the brush being secured by placing theback on the projection 0 and screwing the plate Gr down on it, the pin a being to prevent an undue depression of the back side of the plate G. The object in fixing the plate D between pivots is to enable the attendant to set the brush at an angle with the cutters, and also to enable him to turn the plate up, that he can the more readily adjust the brush on it. The said plate D is held in a fixed position by means of the spring E, which has a catc E upon it, so arranged as to spring in the notch o in the circular segment, &c.

The cutters consist of two circular knives in the nature of saws combined together, and arranged so as to bring their disks in contact with each other, in the manner shown by P P. The arbor of one of these knives is made to pass through the center of the arbor of the other. The two arbors are shown in Figs. 4 and 5 with their respective knives attached. The said knives are made to rotate in opposite directions, as represented by the arrows. The pulleys upon the respective arbors are shown by R R. The arbors are supported in a kind of lathe head, shown by I, which is bolted to the frame A, to which is also bolted the shears A. The requisite motion for the two knives 'is attained by the application of a straight belt to one of the pulleys and a cross belt to the other. The knives have saw edges, but the teeth have no set, so that the disks and teeth are on the same plane, whereby the disk and teeth of the two cutters or knives can work close together, which makes the teeth of the two knives act like shears when the said knives are in motion, the said teeth being filed so as to bring the two edges together. 7

The drawing represents the machine with a brush in it, the back of which is shown by T and the bristles by T. This machine it will be seen consists of two parts, the devices for holding, adjusting and moving the brush constituting the one part, which I shall call the adjusting head, and the de- 'ming head. Neither of these devices or parts would be of any use without the other, in this behalf, but taken together they constitute a very useful and eificient machine.

What I claim, therefore, and desire to secure by Letters Patent, is

1. The combination of what I have above denominated, the adjusting head; with what I have above denominated the cutting or trimming head, in the manner described.

2. Making the said adjusting and trimming heads in the manner described for the purpose specified.
